         2 . The method according to  claim 1 , wherein the acquiring driving information corresponding to the event information from the driving record video comprises:
 extracting the time information from the event information, and searching in the driving record video for a time stamp corresponding to the time information; and   extracting the event content from the event information, and acquiring, at the time stamp, the driving information according to an event category of the event content, wherein the event category comprises at least one of: navigation error information, traffic congestion error information, or road construction error information.   
     
     
         3 . The method according to  claim 2 , wherein the acquiring, at the time stamp, the driving information according to an event category of the event content comprises:
 acquiring a video corresponding to a first set time period preceding the time stamp and/or a video corresponding to a second set time period succeeding the time stamp in the driving record video, in response to the event category being the navigation error information category; acquiring an image corresponding to the time stamp in the driving record video, in response to the event category not being the navigation error information category.   
     
     
         4 . The method according to  claim 1 , wherein the acquiring pending prompt information provided by the electronic map corresponding to the event information and the driving route comprises:
 extracting the location information from the event information, and setting a location stamp corresponding to the location information on the driving route; and   querying the pending prompt information provided by the electronic map corresponding to the location stamp and the time information.   
     
     
         5 . An apparatus for querying information, the apparatus comprising:
 at least one processor; and   a memory storing instructions, the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:   acquiring a driving route, a driving record video, and a record file, the driving route used to record route information corresponding to an actual driving route on an electronic map, the driving record video is used to record video information during an actual driving course corresponding to the driving route, and the record file is used to record at least one piece of event information different from prompt information provided by the electronic map during the actual driving course corresponding to the actual route, the event information comprising time information, location information and event content, and the prompt information comprises at least one of: traffic congestion information, traffic light information, or road construction information;   reading the event information in the record file, acquiring driving information corresponding to the event information from the driving record video, and acquiring pending prompt information provided by the electronic map corresponding to the event information and the driving route, the driving information comprising a driving image and/or a video clip; and   establishing a corresponding relationship between the event information, the driving information, and the pending prompt information, and establishing an information query table based on the corresponding relationship.   
     
     
         6 . The apparatus according to  claim 5 , wherein the acquiring driving information corresponding to the event information from the driving record video comprises:
 extracting the time information from the event information, and searching in the driving record video for a time stamp corresponding to the time information; and   extracting the event content from the event information, and acquiring, at the time stamp, the driving information according to an event category of the event content, wherein the event category comprises at least one of: navigation error information, traffic congestion error information, or road construction error information.   
     
     
         7 . The apparatus according to  claim 6 , wherein the acquiring, at the time stamp, the driving information according to an event category of the event content comprises:
 acquiring a video corresponding to a first set time period preceding the time stamp and/or a video corresponding to a second set time period succeeding the time stamp in the driving record video, in response to the event category being the navigation error information category; acquire an image corresponding to the time stamp in the driving record video, in response to the event category not being the navigation error information category.   
     
     
         8 . The apparatus according to  claim 5 , wherein the acquiring pending prompt information provided by the electronic map corresponding to the event information and the driving route comprises:
 extracting the location information from the event information, and setting a location stamp corresponding to the location information on the driving route; and   querying the pending prompt information provided by the electronic map corresponding to the location stamp and the time information.   
     
     
         9 . A non-transitory computer readable storage medium storing a computer program, wherein the computer program, when executed by a processor, cause the processor to perform operations, the operation comprising:
